Rally dash oil pressure gauge issue.

Keep in mind the circuit pulls a lot of current, particularly when the gauge is reading high. You should have 5 or 10 watt resistors. If you use a low wattage resistor, like a 1/4 watt, don’t leave it hooked up long or it will burn up and change value. also don’t touch it or it will burn your fingers, don’t ask how I know...
